Stationary

i dont know how to do a perfect disc but you could probably make a fairly good makeup of one with a custom shape.

but how do i program a stationary - it is not explicit in the breve documentation.

is it just like a mobile? could anyone provide simple example code

sorry to be a burden

A number of the included breve demos have Stationary objects. The SwarmEvolve-1.0 simulation, for example, has this code:

        floor = new Stationary.
        floor register with-shape (new Cube init-with size (100, 2, 100)) at-location (0, -5, 0).

To get a disc shape, you'll want to use the class PolygonDisk, which is included in Shape.tz. No need to use CustomShape, as this is a standard built-in shape.

In that case, you'll replace the "Cube" creation above with something along the lines of:

new PolygonDisk init-with radius 5.0 sides 20 height 0.1.

Of course, you'll want to play with those parameters until you get the shape you're looking for.

carrying on from gregger's theme...

are stationary objects completely passive?

i am wanting change their colour as i run from my simulation.

would it be better to us a non moving mobile?

thanks
